U.S. star swimmer Caeleb Dressel has beaten his own world record in the 100- meter butterfly at the Tokyo Olympics. The 24-year-old led for the entire two-lap sprint and clocked it in 49.45 seconds. After winning, he celebrated with his closest competitor, Kristof Milak from Hungary. "It was faster than I thought it was going to be," Dressel said. "I'm sure it was really fun to watch for everybody, it was certainly fun to take part in." Dressel also took gold in the 100 meter freestyle earlier this week. Copyright 2021 NPR.
